yeah :)

if you're really confused, see the commits when I added Apache::MPM

the bulk of the main commit consists of the tests, but the interesting
changes are at the bottom.  if you just follow that pattern you should
be able to add the module of your choice.

yeah.  IIRC we were leaving it to doug and his hacked version of C::Scan
to generate the official scan, with the rest of us modifying it as you
see in the commits.
